Ko propo transmitter with Spektrum module users

[4nd7]

Got a ko Helios and Esprit 3 transmitters that both use the same spektrum module. I've been using the module and Helios for years without problem all except for a gradual increase in glitching that was cured with a new aerial. Recently i've used the same module in an ko Esprit 3 and noticed glitching on throttle and even a momentary steering reverse once but not every run.

Its similar problems with a few models so must be something to do with either the transmitter or module but was wondering if it could have anything to do with the response setting in the transmitter? On the helios there is a switch behind the module for nomal of fast response but on the esprit 3 there are about 4 speed setting in the options menu ranging from normal to ultra. Wondering if anyone has had experiance with these response setting being too fast for the module to cope with and if so what setting to have it on?
